JOHN H. JONES, OF ATLANTA, GEORGIA.

AUTOMATIC SPRINKLER.

Application filed October 22., 1925. Serial No. 64,178.

This invention relates to sprinklers such as are used in the well known sprinkler system of fire protection in houses, mills'and other structures.

The principal object of the invention is to provide an improved construction of sprinkler whereon the fusing ot' a fusible link will permit a cutoii valve to open and simultaneously place a spreader beneath the valve and sprinkler.

With the above and other objects in view, as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations oi fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and;

Figure 1 shows a section through ceiling having a sprinkler pipe arranged below it.

Figure 2 is a side elevation of the improved fire extinguisher, the extinguisher being such that it may be suspended in any desired position.

Figure 3 is a View at right angles to Figure 2 showing the valve in open position.

Figure 4 shows a modified form of the spreader.

Whether this device he used with a sprinkler pipe or with a tank 11 there is provided in connection with the pipe or tank one or more outlet valves 12 having each a handle 13 whereto is connected a lever 14 to the end of which is secured one end of a chain 15. The other end of the chain 15 has a heavy ball 16 of suitable size so that when it is released. it will turn the valve to open position, Figure 2 shows the normally closed position and Figure 3 such open position. Under normal circumstances this ball is suspended by a fusible link 17 engaging a hook 18.

On the lever 14 is carried a spreader which consists of a dished plate 19 and the spreader is position-ed to rest, when the valve is open, beneath the outlet end of the valve 12. Thus the fusing of the link 17 releases the ball, which by force of gravity or drop, opens the valve and also brings the spreader in position.

In the form shown in Figure 2 it is to be understood that the extinguisher shown is partially filled with a chemical fire ex fluid being under prestinguishing fluid, the

air at the top of the sure of compressed tank.

In the form shown in Figure 4 the spreader is carried by a collar 20 clamped around the outlet end of the valve and is thus permanently in position. The interior of the spreader may be corrugated or provided with other means that will assist in breaking up the stream of chemical tire extinguishing fluid and causing it to properly spread.

There and efiicient device of the kind and for the purpose specified.

Having thus described the invention, is claimed as new, is:

1. In an automatic sprinkler device, a discharge nozzle, a normally closed rotary valve controlling the flow of fluid thereto and having a stem, a lever connected to said stem for operating the valve, a spreader carried by and movable with said lever, means for actuating said lever, and a fusible link normally preventing operation of said lever, said parts being so arranged that on fusing of said link the actuating means will move the lever to open the valve and to position the spreader in the path of discharge from said nozzle.

2. In an automatic sprinkler device, a vertically disposed discharge nozzle, a normally closed rotary valve controlling the flow of fluid thereto and located at the upper end of said nozzle with the axis of rotation horizontal, said valve having an operating stem projecting laterally from the valve and axially alined with the rotative part of the valve, a normally horizontal lever fixed to said stem at right angles to the axis thereof, said lever being of greater length than. the nozzle and movable to vertical position to open said valve, a spreader fixed at right angles to the side of the lever adjacent the valve and positioned on the lever to lie in axial alinement with and in spaced relation to the nozzle upon the lever being positioned vertically, means for moving the lever from horizontal to vertical position, and a fusible link normally preventing operation of said means.

In testimony whereof I aflix my signature.

has thus been provided a simple described what JOHN Hi JONES till
